Financial Information

Excluding (i) budgetary ,(ii) volumetric, (iii) revenue from sales and services including IEPS, (iv) domestic sales

including IEPS, (v) petroleum products sales including IEPS, and (vi) operating income including IEPS information,

the financial information included in this report is based on unaudited consolidated financial statements prepared in

accordance with Normas de Informacion Financiera (Mexican Financial Reporting Standards, FRS) -formerly Mexican

GAAP- issued by the Consejo Mexicano de Normas de Información Financiera (CINIF).

— Based on FRS B-10 "Inflation effects", 2010 and 2011 amounts are expressed in nominal terms.

— Based on FRS B-3 "Income Statement” and FRS “C-10” Derivative Financial Instruments and Hedging

Transactions”, the financial income and cost of the Comprehensive Financial Result include the effect of financial

derivatives.

— The EBITDA is a non-U.S. GAAP and non-FRS measure issued by CINIF.

Budgetary information is based on standards from Mexican governmental accounting; therefore, it does not include

information from the subsidiary companies of Petróleos Mexicanos.

Foreign Exchange Conversions

Unless otherwise specified, convenience translations into U.S. dollars of amounts in Mexican pesos have been made

at the established exchange rate, at December 31, 2012, of Ps. 12.8521 = U.S.$1.00. Such translations should not be

construed as a representation that the peso amounts have been or could be converted into U.S. dollars at the

foregoing or any other rate.

Fiscal Regime

Since January 1, 2006, PEMEX has been subject to a new fiscal regime. Pemex-Exploration and Production’s (PEP) tax regime

is governed by the Federal Duties Law, while the tax regimes of the other Subsidiary Entities continue to be governed by

Mexico’s Income Tax Law. The most important duty paid by PEP is the Ordinary Hydrocarbons Duty (OHD), the tax base of

which is a quasi operating profit. In addition to the payment of the OHD, PEP is required to pay other duties.

Under PEMEX’s current fiscal regime, the Special Tax on Production and Services (IEPS) applicable to gasoline and diesel is

regulated under the Federal Income Law. PEMEX is an intermediary between the Secretary of Finance and Public Credit

(SHCP) and the final consumer; PEMEX retains the amount of IEPS and transfers it to the Federal Government. The IEPS rate is

calculated as the difference between the retail or “final price”, and the “producer price”. The final prices of gasoline and

diesel are established by the SHCP. PEMEX’s producer price is calculated in reference to that of an efficient refinery

operating in the Gulf of Mexico. Since 2006, if the final price is lower than the producer price, the SHCP credits to PEMEX the

difference among them. The IEPS credit amount is accrued, whereas the information generally presented by the SHCP is cash-

flow.

Hydrocarbon Reserves

Pursuant to Article 10 of the Regulatory Law to Article 27 of the Political Constitution of the United Mexican States

Concerning Petroleum Affairs, Pemex-Exploration and Production’s hydrocarbon reserves estimates as of January 1, 2012,

were reviewed by the National Hydrocarbons Commission (which we refer to as the NHC). The NHC approved our hydrocarbon

reserves estimates on February 24, 2012. The registration and publication by the Ministry of Energy, as provided in Article 33,

paragraph XX of the Organic Law of the Federal Public Administration, is still pending.

As of January 1, 2010, the SEC changed its rules to permit oil and gas companies, in their filings with the SEC, to disclose not

only proved reserves, but also probable reserves and possible reserves. In addition, we do not necessarily mean that the

probable or possible reserves described herein meet the recoverability thresholds established by the SEC in its new

definitions. Investors are urged to consider closely the disclosure in our Form 20-F and our annual report to the Mexican

Banking and Securities Commission (CNBV), available at http://www.pemex.com/.

Forward-looking Statements

This report contains forward-looking statements. We may also make written or oral forward-looking statements in our periodic

reports to the CNBV and the SEC, in our annual reports, in our offering circulars and prospectuses, in press releases and other

written materials and in oral statements made by our officers, directors or employees to third parties. We may include

forward-looking statements that address, among other things, our:

— drilling and other exploration activities;

— import and export activities;

— projected and targeted capital expenditures; costs; commitments; revenues; liquidity, etc.

Actual results could differ materially from those projected in such forward-looking statements as a result of various factors

that may be beyond our control. These factors include, but are not limited to:

— changes in international crude oil and natural gas prices;

— effects on us from competition;

— limitations on our access to sources of financing on competitive terms;

— significant economic or political developments in Mexico;

— developments affecting the energy sector; and

— changes in our regulatory environment.

Accordingly, you should not place undue reliance on these forward-looking statements. In any event, these statements speak

only as of their dates, and we undertake no obligation to update or revise any of them, whether as a result of new

information, future events or otherwise. These risks and uncertainties are more fully detailed in PEMEX’s most recent Form

20-F filing with the SEC (www.sec.gov), and the PEMEX prospectus filed with the CNBV and available through the Mexican

Stock Exchange (www.bmv.com.mx). These factors could cause actual results to differ materially from those contained in any

forward-looking statement.
